LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 372,997, dated November 8, 1867.

Application filed March 3,1887. Serial No. 229,56'2.

To all whom it may concern.'

Be it known that I, ALBIN WARTH, a citizen of the UnitedStates, residing at Stapleton, in the county ot Richmond and State of New York, have invented new and useful Improvements in Lubricators, of which the following is a specification.

This invention relates to a lubricator which can be adjusted so as to deliver any desired quantity of oil, and which is provided with an alarm to indicate automatically when all the oil is discharged from the measuring-chamber.

The invention-consists of certain new combinations of parts, as fully pointed out in the following speciication and claims, and illustrated in the accompanying drawings, in which- Figure 1 represents a horizontal section in the plane x w, Fig. 3. Fig. 2 is a transverse vertical section in the plane y y, Fig. l. Fig. 3 is a longitudinal vertical section in the plane zz, Fig. l. Fig. 4 is a detached side elevation of the plunger and barrel for measuring and delivering the oil, on a larger scale than the previous figures. Fig. 5 is a transverse section in the plane rv Fig. 4. Fig. 6 is a transverse section in the plane y y', Fig. 3.

- Fig. 7 is a transverse section in the plane zz,

Fig. 3. Figs. 8 to 14 are details, which will be referred to as the description progresses. Fig. 15 is a longitudinal section of a modification.

Similarletters indicate corresponding parts.

In the drawings, the letter A designates the oilicistern, which is open at the bottom and communicates freely with thesupply-chamber B. rIhis supply-chamber is provided at one end with a rigid head, a, while its opposite end is open and provided with a movable head, C, which, however, is firmly clamped between the supply-chamber and the barrel D by means ot' screws b b, Fig. l. On the rigid head a of the chamber B is formed a stuffing-box, c, and through this stuftingbox extends a rod, E, on which is secured a crosshead,.F, which connects with the driving-shaft G, Fig. 1, so that by turning said shaft a reciprocatling motion is imparted to the rod E. -1 In the example shown in the drawings the driving-shaft G carries two eccentrics, ci d, which connect by rods e e with the cross-head (No model.)

F, but I do not wish to confine myself to these precise means for imparting to the rod E a reciprocating motion. From the cross-head F risesa standard, f, provided with an eye which g lits a stud, g, lirmly secured in the rigid head is formed a disk, G', Figs. l, 3, and 7, whichv is provided with a series of holes, g2 g y 023 y gl5 g2 g, and on the outer end ofthe rod E is fitted a sleeve, H, which carries the index I. The sleeve H is tted upon the rod E by means of a feather-key, h, and the index I is exposed to the actionof a spring, z', which has a tendency to force the point of said index toward the disk G. The casting which forms the cross-head F, the standard f, and the disk G'abuts against a shoulder, j, formed on the y rod E, Fig. 3, and on the outer end of this rod is cut a screw-thread to fit a nut, J, which serves to vact upon the sleeve H. When this nut is turned back, the sleeve, together with the rod E, can be turned until the pointof the index engages one of the holes-for instance, g .in the disk G-and when the nut .lis then screwed up the rod E is firmly connected to the cross-head F, so that it Acannot turn round, and is compelled to partake of the movements of the cross-head.

The devices for graduating the quantity of oil delivered foreach stroke of the mechanfV ism consist, principally,ofa measuringchamber, a plunger working in this measuring chamber, relief-openings, through which the surplus oil iiows back from the measuring chamber into the supply-chamber, and a relief-regulator.

Inthe example shown in Fig. 3 of the drawings the relief-regulator is made in the form of a shell, L, which is ground upon a tapering plug, M, projecting from the movable head C of the supply-chamber B. A pin, k, which projects from this relief-regulator,engages an arm, K, which is secured on the inner end of the rod E, and a spring, N, servesto retain the relief-regulator L on the plugM. In t-he example shown in the drawings this spring is made in the form of a disk, Fig. 1l, and it bears ICC against a shoulder, a, formed in the interior of the supply-chamber. The plug M is bored out to form the measuringchamber O, and into this measuring chamber is tted the plunger P,whicl1 is secured in the inner end of the rod E by means of a pin, 0, the connection between the plunger and the rod being ofA such a nature that the plunger has sufficient freedom to accommodate itself to such disturbances in the position of the rod E, which may be caused by the inequalities of the packing in the stuffing-box, and which, without the hinge-connectionbetween the stuffingbox and the valve -seat, would be liable to cause the plunger to bind in the measuringchamber. In the relief-regulator L is formed a circular-channel, Z, which is closed at the outside by a sieve, Z, Figs. 3, (3, and 12, and which, through the openings in said sieve, communicates with the supply-chamber B. From the circular channel Z extends a groove, Z2, to the end of the relief-regulator next the movable head C. The plug M is provided with two or more holes, m', Figs. 3 and 6,which communicate with the circular-channel Z' in the relief regulator L, and through which the meastiring-chamber O is brought into communication with the supply-chamber B. In the plug M are a series of reliefopenings, m2 mi" mi min ar"l m"`5 nf mfwhich are graduated, or, in other words, so placed that the quantity of oil permitted to tlow from the measuringchamber back into the supply-chamber, is more or less according to the relief-opening which is brought into action.

The outer end of the measuring-chamber O is closed by a valve, Q, which is forced up against its sentq by a spring, R. This spring is, by preference, made in the form ofa spider, as shown in Fig. 10, and itacts upon the valve Qby means ot' a stem, S, which is guided in the barrel D, and which is provided with a foot, s, which fits loosely into a cavity in the valve Q, and the end of which is rounded, so that it allows the valve sufficient freedom of motion to accommodate itself to its seat q.

The stem S is provided with a series of grooves, siii, which extend in the direction of its axis, (see Figs. S and 9,) so that if the barrel D becomes iilled with oilaud the stem is moved in and out the oil can escape through said grooves. The stem S is bored out to receive a rod, T, which extends through astuft'- ing-box, dit, and the outer end of which bears against a lever, U, which swings ongudgeons a, Fig. 14, and the upper end of which carries the clapper V, which is intended to act upon the bell \V. The lower end of the lever U is exposed to the action of a spring, v, which has a tendency to throw the clapper V back away from the bell \V.

From the foregoing description it will be seen that the valve Q is seated in the end of the measuringvchamber and that the plunger I? moves forward close to the valve, so that the same is enabled to force all the oil which has entered the measuringchamber at the backstroke out of said chamber at its iforward stroke; and it will be further seen that when the nut J, Fig. 3, is turned back and the index I is drawn away from the disk G the rod E can be turned round, and by turning this rod the relief-regulator L is also turned on theplug M. If the rod E is turned so as to bring the index I opposite the hole g2 in the disk G', the reliefregulator L is brought into that position in which its longitudinal groove L2 covers the relief-opening my in the plug M. This is the position representedinFig. 3. If the plunger l) is set in motion, it moves back just beyond the circular groove Z in the relief-regulator L, leaving the oil in the supply-chamber B free to pass into the mcasuring-ctu1mber O, through the circular groove l and the openings m', and to fill up the space in front of the plunger. Vhen the plunger l) begins its return-stroke and passes the openings m in the plug M, all the oil contained in the measuring-chamberO in the space between the openings m and the valve Q would be forced out through said valve into the deliverypipe X if it was not Vfor the relief-openings mIl m m' m2, Sec., in the plug M. But since (in the position shown in Fig. 3) the opening mi communicates, through the longitudinal groove Z2, with the supply-chan1- ber B, all the oil between the front end of the plunger and the reliefopening mi will be forced out of the measuring-chamber and only the oil contained in the space between the relief-opening mi and the valve Q, which may be termed the effective space ot' the measuring-chamber, will be forced ont into the-delivery-pipe. This effective spaceof the measuring-chamber can be increased or decreased by adjusting the relief-regulator L. If the index I is set to engage the hole g2 in the disk G', the longitudinal slot Z2 of the relief-regula tor L covers the relieffopening m2 and the effective space of the mensuring-chamber is reduced to a minimum, so that only a drop of oil will be driven out of the same for every stroke of the plunger, while by setting the index so as to engage the hole g'" in the disk G the effective space ot' the measuring-chamber is increased to its maximum.

The oil, in being forced out of the measuring-chamber, must necessarily force thc valve Q back away from its seat q, and whenever the valve moves back it actuates the lever U through the rod T; but if the supply of oil has given out, or if from some other cause no oil is driven out of the measuring-chambcr by the plunger I), the lever U remains stationary. By these means this lever becomes a visible or (if it is provided with a clapper) an audible signal,which indicates the correct action ofthe lubricator.

As already stated, the rcliefregulator L, as represented in Figs. 3, 6, and l2, has the form of a shell, which is ground upon the plug M, and which is turned in order to bring the different relief-openings into action. Instead of adjusting the relief-regulator by imparting to it a rotary movement, said relief-regulator IOO ICS

can be so constructed that it can be adjusted by imparting to it a rectilinear sliding movement. n This construction is illustrated in Fig. 15, in which B represents the supply-chamber. O is the measuring-chamber. Q is the valve of the measuring-chamber. P is the plunger, which works in the measuring-chamber. M is the plug, which is provided with one or more holes, m', through which oil is admitted from the supply-chamber B to the measuringchamber whenever the plunger P is drawn back beyond said holes. 4m2 m21 m22 m23 are the relief-openings,whicl1 extend through the side of the plug M at different distances from the discharge-opening of the measuring-chamber. The plug M is cylindrical, and on it is fitted tlie'relief-regulator L, which is connected toa shaft, L', that has its bearings in the sides of the supply-chamber B, and on which are secured slotted arms ZS ZS,which engage with pins Z9, projecting from the sides of the relief-regulator L. By turning the shaft L the reliefopenings m2 m21 m'z2 in can be openedor closed. In the position shown in Fig. l5 all the reliefopenings are open. Iftlle plunger P is moved back beyond the hole m', the measuringchamber O lills with oil, and if the plunger is moved forward toward the valve Q,the oil infront of the plunger will be forced out through the relieiopenings until the front end of the plunger has passed the reliefopening mi. The oil between this opening and the valve Q is driven out through the valve. If the relief-regulator L is moved to cover the opening m2 all the oil contained in the measuring-chamber between the opening m21 and the valve is driven out ,through the valve, and so on, as will be readily understood from the foregoing description.
